Thank you was very clear and useful.
AMAZING information but your voice is very low
Bestest ever!!!!
Wonderful video. You are a pure gem in teaching geography. No one can explain in such a lucid manner except you. Cheers to joy of learning.
ive been finding black rocks near my house that share alot of similar qualities of those in the video, i feel it is kinda wierd on how ive been picking them all up and finding more later on in the area,
Now I understand that I work in factory in boiling machine and I thought hard to ignite because of wet coal (got drenched from raining) and I noticed that has difference of coal I saw like shiny one that u can crush it by stumping on it and hard one has very dark but not shiny that's very hard so I end up using hammer to crush it.
Thanks you help me in school

World coal consumption was about 7.25 billion tonnes in 2010 The price of coal increased from around $30.00 per short ton in 2000 to around $150.00 per short ton as of September 2008. In early 2015, it was trading near $56/ton.
